SAIC-GM-Wuling Automobile (SGMW), a prominent Chinese automaker, has initiated a recall of 1,116 units of its popular electric vehicle, the Baojun Yep. This recall action stems from a software bug discovered in the Electronic Brake Assist (EBS) system of vehicles manufactured between April 20th and June 14th, 2023.
The crux of the issue lies in a flawed date calculation within the EBS software. The system utilizes a 365-day calendar for timing calculations, which inevitably leads to errors when processing the final day of a leap year. This miscalculation disrupts communication within the EBS, potentially resulting in brake assistance failure. Such a malfunction poses a significant safety risk to the vehicle occupants.
To rectify this issue, SGMW will implement a software upgrade for all affected vehicles. Notably, some vehicles have already received this upgrade and will not require further action. The company will proactively inform affected customers through various channels, including registered mail, phone calls, and other communication methods. These notifications will include detailed instructions on how to schedule and receive the necessary software update.
The Baojun Yep, a compact electric SUV specifically designed to appeal to young drivers, has gained popularity for its blend of practicality and playful aesthetics. Available in two trim levels – the Flagship Edition and the Deluxe Edition – the Yep boasts a commendable 303 km range (CLTC standard) and supports rapid charging, achieving a 30-80% charge in just 35 minutes. This makes it an ideal choice for urban commutes and short trips.
Despite its compact dimensions (measuring only 3381 mm in length), the Yep incorporates several innovative design features. These include unique side-opening rear doors reminiscent of a refrigerator and a 35-liter front trunk that can be converted into a refrigerated compartment. The interior further emphasizes a youthful and tech-centric approach with a "JoyBox" setup featuring a 10.25-inch twin-screen display and customizable dashboard elements.
The Yep's tech-savvy credentials are further bolstered by its inclusion of the KiOS software platform, advanced driver-assistance systems (ADAS) from DJI's LingXi suite (including automated parking), and a 360-degree surround-view camera. A particularly unique feature allows drivers to share messages or images with others via the rear screen, fostering a sense of connectivity and social interaction tailored to the preferences of young, smartphone-centric consumers.
This recall serves as a reminder of the critical importance of robust software development and rigorous quality control within the rapidly evolving electric vehicle market. While the issue with the Baojun Yep appears to be a relatively isolated incident, it underscores the need for continuous vigilance and proactive measures to ensure the safety and reliability of these increasingly complex vehicles.
